The function f(x) = − x^2+ bx +1 is shown in the graph. What is the value of b?

denis-greek [22]

Answer:

b = 4

Step-by-step explanation:

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

here ( h, k ) = (2, 5 ) , then

y = a(x - 2)² + 5

to find a substitute any point on the parabola into the equation

using (0, 1 ) then

1 = a(0 - 2)² + 5 ( subtract 5 from both sides )

- 4= a(- 2)²= 4a ( divide both sides by 4 )

- 1 = a

then

y = - ( x - 2)² + 5

= - (x² - 4x + 4) + 5

= - x² + 4x - 4 + 5

= - x² + 4x + 1 ← in the form ax² + bx + c

with b = 4

Can someone help? 20 points!

V = $\frac{4}{3} \pi r^{3}$

905 = $\frac{4}{3} \pi r^{3}$

2715 = 4π r³

$\frac{2715}{4\pi } = r^{3}$

216 = r³

$\sqrt[3]{216} = \sqrt[3]{r^{3} }$

6 = r

$i = (\frac{p1}{p2} )^{\frac{1}{n}} - 1$

$i = (\frac{200,000}{3,000} )^{\frac{1}{(2012-1945}} - 1$

$i = (\frac{200}{3} )^{\frac{1}{(67}} - 1$

i = (66.67)⁰¹⁵ - 1

i = 1.065 - 1

i = 0.065

i = 6.5%

Answers: r = 6, i = 6.5%

A square patio has an area of 200 square feet how long is each side to the nearest tenth

professor190 [17]

Answer: THERE ARE TWO WAYS OF DOING THIS!!

Key words: square, area, 200 square feet

Area: what × what = 200?

Step-by-step explanation:

A square has 4 sides, and all of its sides are of equal length.

So if a square has 4 sides, and its total area is 200 square feet, what do you have to do?

You have to divide the area by 4!

So 200 ÷ 4 = ?

200 ÷ 4 =50

So each side is 50 feet long.

In this scenario, there are no tenths because each side is exactly 50 feet. If you wanted the lengths to the nearest tenth, your answer would be 50.0

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If patio is a square, basically it says the area is $A=a^{2}$ where a is equivalent to one side of the square.

Now that we know that a = 200, we will be able to solve the expression

$a^{2} =200$

a= $\sqrt{200}$

a=14.1421, which is the square root of $\sqrt{200}$

Now we rounded to the nearest tenths

a≈14.1

We rounded to 14.1 because the rounding rule is: <em>4 and below rounds down, 5 and above rounds up.</em>

The result is 14.1
